OIL-CAN ATTACHMENT,

Specification of Letters Patent.

ratenteaoet. 14,1913.

Application filed March 21, 1912. Serial No. 685,255.

To all whom t may concern Be it known that T, LOUIS H. BURCI-m'ri, acitizen of the United States, residing at Cashion, in the county ofKingfisher' and State of Oklahoma, have invented certain new and usefulImprovements in Oil-Can Attachments; and T do declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to an improved attachment for oil cans.

One object of the invention is to provide an oil regulating feedattachment which may be applied to any can already manufactured withoutany change being made in the structure of the can.

Another object is to provide such an attachment which may be usedequally well with an oil can which has lost the spring in its bottom.

Another object is to provide a feeding attachment for oil cans adaptedto extend through and project at one end beyond the free end of the canspout to provide for the use of said feeder end as a cleaner for the oilholes of machinery, and when the oil is forced out of the can it willrun down said projecting feeding end and the operator can readily seewhen the oil is flowing properly.

Another object is to provide an oil feeder having adjustable regulatingmeans to permit more or less oil to flow as may be de- Sii-ed and whichis especially useful in warm weather when the oil is thin and flowsfreely.

With these and other objects in view, the invention consists of certainnovel features of construction, combination and arrangement of parts aswill be more fully described and particularly pointed out in theappended claim.

In the accompanying drawings: Figure 1 represents a vertical sectionalview of a can equipped with this improved attachment, parts of theattachment being broken out; Fig. 2 is a similar view showing the can ininverted position, such as is assumed when in use; Fig. 3 is a sideelevation of another form of the invention; Fig. A is a vertical sectionthereof.

In the embodiment illustrated in Figs. 1 and 2, a can l is shownprovided with a bottom 2 of resilient metal which may be forced inwardfor actuating the feed device hereinafter described, said bottom readilyexpanding and assuming its normal position after actuation in the mannerordinary in cans of this character. This spring bottom while desirableis not necessary for use in connection with this attachment as saidattachment may be equally well em ployed in connection with cans thebottoms of which have lost their spring.

A spout 3 of ordinary construction is threaded in the usual manner atits lower end in an interiorly threadedneck of the can 1.

This improved valve or feeding attachment comprises a stem 5 preferablyconipcsed of two members 6 and 7 adjustably connected and extensible tovary the length of the stem 5 as sho-wn. These members comprise atubularlower member 6 threaded interiorly and exteriorly and in which ismounted an upper smaller member 7 which is threaded for the greaterportion of its length and adapted tc be screwed into the member 6, thefree outer end of said member 7 being preferably reduced and providedwith smooth faces on which may be stamped any desired inscription.Mounted on the threaded portion of the member 7 is an inverted coneshaped valve 8 having a threaded bore extending therethrough to providefor its adjustment on the member 7 and which is adap-ted to lit in theouter end of the can spout and provide a suitable closure therefor, andwhich may be adjusted at any desired point on said member 7 to regulatethe quantity of oil permitted to iiow from said spout in a manner to bedescribed.

A nut 9 is mounted on the lower member 6 of the stem 5 and is adjustablethereon to vary the tension of a coil spring 10 which is mounted on saidmember 6 between said nut 9 and the inner end of the can spout. Nhen itis desired to increase the tension of the spring 10, the nut 9 isscrewed up on the member 6 whereby the valve member 8 will also be heldnormally in closed position fitting tightly within the mouth of thespout prior to the depression of the can bottom by the operato-r. Acushion 11 is secured to the lower end of the member 6 and is adapted tobear on the bottom of the can, forming a receiving socket or seat forsaid stem member 6. This cushion 11 is preferably composed of felt orany other similar material and is designed to prevent wear on the canbottom such as would occur during the operation of the valve, or feedingattaehment.

The stem member 7 is preferably provided with a plurality oflongitudinally spaced oil cups 12 which'are adapted to hold t-he oil andwhen the 'stem is lmoved forwardly forces the oil out through the canspout which is especially desirable in cold weather when the oil isthick.y

In the operation of the device when a small quantity of oil is. desiredtoy be fed from the can spout the cone shaped valve member 8 is movedinwardly on the member 7 and when more oil.` is required it is movedoutwardly. This valve 8 is so positioned on the ste-m 5 thatJK it alwaysremains within the spout of; the can .and thereby holds the feederalways in the center of the can bottom. Nhen the oil is. pumped up' bypressure exerted on thebottorn of the can the cups 12 catchA theoil andforce it out.

through the spout.

By arranging the spr-ing on the stem 5 i between the nut 9 and the innerend of the spout of the can, said spring when so positioned operates inthe same manner as a re* silient can bottom and thus adapts the deviceto be used equally well with a can which has lost the spring in itsbottom.

In Figs. 3 and 4; the regulation feed attachment is` shown especiallydesigned for use in cans having crooked or curved spouts, such as areemployed by railway engines and thev like. This device is constructedsimilarly to that shown in Figs. 1 and 2, except that the curved spout 8is provided with a tubular arm 13 extending at an acute angle preferablyfrom a point near its inner end and communicating with the interior ofthe can spout to provide for the insertion of a curved stem or plunger14. This plunger' projects at opposite ends beyond the outer end of thespout 8 and the free end of the arm 13 respectively. The end of the"plunger which projects beyond the spout end is threaded and providedwith an inverted cone-shaped valve 8 similar to valve 8 and is designedto normally provide a tight closure for the mount of the can spout. Acoiled spring 15 is mounted on the other end of the plunger 14 betweenthe free end j of the arm 13 and the nut 16 on said plunger end, whichlatter is threaded to receive the nut which is designed to adjust thetension of said spring. A push button 16 is secured to the end of theplunger which projects through the arm 13 and is adapted to be vpressedby the thumb of the operator for forcing the plunger forward against thetension of the spring 15 to offset the valve 8" and permitapredetermined quantity of oil to iiowk out through the spout, thequantity being controlled by the adjustment of the.

valve 8 on the outer end of the plunger.

I claim as my invention: An oil feeding attachment for cans comprising asectional stem the sections of which arey connected for longitudinaladjustment, one of said sections having screw threads near its outerend, said end' beyond said threads being reduced and provided withsmooth faces, an inverted cone shaped valve adjust-ably mounted on thethreaded portion of said stem section, a nuty mounted on the free end ofthe other section and adjustable thereon7 and a coiled spring mounted onsaid last mentioned section and adapted to bear at one end on said nutby means.

of which the tension thereof is varied,fand a cushioning element securedtov the terminal of said stem section.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
